<p><a class="link" href="GDataCommentable.html" title="GDataCommentable"><span class="type">GDataCommentable</span></a> is an interface which can be implemented by commentable objects: objects which support having comments added to them by users,
such as videos and photos.</p>
<p>Comments may be queried, added and deleted. Note that they may not be edited.</p>
<p><a class="link" href="GDataCommentable.html" title="GDataCommentable"><span class="type">GDataCommentable</span></a> objects may not support all operations on comments, on an instance-by-instance basis (i.e. it's an invalid assumption that if,
for example, one <a class="link" href="GDataYouTubeVideo.html" title="GDataYouTubeVideo"><span class="type">GDataYouTubeVideo</span></a> doesn't support adding comments all other <a class="link" href="GDataYouTubeVideo.html" title="GDataYouTubeVideo"><span class="type">GDataYouTubeVideo</span></a>s don't support adding comments either).
Specific documentation for a particular type of <a class="link" href="GDataCommentable.html" title="GDataCommentable"><span class="type">GDataCommentable</span></a> may state otherwise, though.</p>
